I'm working on a 4 years legacy codebase with 500k LOC.
It's time to integrate @DCMAnalyzer.
I prepared a AI workflow, that will spawn a lot a subagents.
Take the bet, will I one shot this ?

🤔 Most teams can tell when a Flutter method feels too complex. The problem is that “too complex” is subjective.
Read "Cyclomatic Complexity, #Flutter Guide" & learn how to shield your code and to refactor it down and protect your team now & later!

✨ Still doing manual null checks in your collection literals?
DCM’s prefer-null-aware-spread rule warns when you could use ...? in your #Flutter code instead.

Advanced metrics configuration in DCM is where metrics become practical.
You’re not limited to one global threshold. You can tune metrics for legacy code, new features, widget-heavy UI, critical paths, and even dashboards-only tracking.
In this guide, learn how you can do it 👇
Don’t disable a metric if the default threshold does not really work, instead:
✅ Use entries for stricter new code
✅ Give legacy folders a temporary threshold
That way, new code improves without blocking every release because of old code.
When it comes to #Flutter widget code, there are different expectation compared to plain domain logic.
That’s why our guide separates widget metrics from non-widget metrics, so UI, services, and domain logic are measured differently: dcm.dev/docs/guides/advanced…
🚀 Quality code tip: Use the variable you already created.
It's easy to miss, but the "use-existing-variable" rule catches repeated expressions when a variable already exists.
🪧 Less code
🔁 Less duplication
✅ Fewer inconsistencies

🎉 A case study with Appinio was published!
Appinio is a fast-growing global market research platform. Their mobile team delivers production-grade Flutter apps and uses DCM to maintain high development velocity without compromising long-term maintainability.
How? 👇
The DCM baseline keeps the team on top of legacy issues, separate from new code.
Real-time IDE feedback enforces consistent structure and patterns, and GitHub Actions automation ensures that no PR is merged without passing DCM checks.
DCM has delivered measurable improvements for Appinio:
⚡ faster, smoother PR reviews
🐛 fewer runtime issues
✅ increased code consistency
👋 easier onboarding
🔄 continuous improvement without blocking development

Heads up, there’s a code freeze a-comin! 🥶💙
To move Material and Cupertino downstream to the stable branch in flutter/packages, we’ll be freezing these libraries with our next release cut-off on April 7
